In many practical structural applications, unknown states, inputs and parameters are
present. However, most methods require one or more of these variables to be known in …

This paper is focused on the application of the fundamental model reduction techniques
used in structural dynamics to flexible multibody systems. In particular, an effective …

Abstract The Absolute Nodal Coordinate Formulation (ANCF) can be used to model a
flexible multibody system subject to both overall motions and large deformations. With an …

Nonlinear finite element methods such as isogeometric analysis and absolute nodal
coordinate formulation can be applied to modeling the flexible multibody systems (FMBS) …

Many applications require fast and even real-time multibody simulations. Until recently,
strongly simplified models were used in order to reach real-time constraints. A novel system …

This study proposes deployable units driven by elastic hinges and a double‐layer hoop
deployable antenna composed of these units. A rational modeling method based on the …

Modeling a flexible multibody system employing the floating frame of reference formulation
(FFRF) requires significant computational resources when the flexible components are …

A novel model order reduction scheme for nonlinear finite element (NL‐FE) structural
dynamics models is proposed in this work, which enables an overall accelerated model …
